What happens if I try this method with crew emblems?

FasterThanYou

Let´s say I make a crew just to use its emblem, without any actual members besides me. Let´s say my first emblem is a number inside a circle, which I want to use for a particular car.

What happens if then I change the emblem to anything else I want in another car? Does my first car lose its emblem? Does it automatically change to the new one? Can I have different emblems in different cars if I keep switching my emblem?
